  Introduce `coverages'. Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only. Code for handling selected OpenType features (this is, actually using the data in `afcover.h') will follow. * devel/ftoption.h, include/config/ftoption.h (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros. (AF_Coverage): New enumeration (generated by `afcover.h'). (AF_StyleClassRec): New member `coverage'. (AF_DEFINE_STYLE_CLASS): Updated. * include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage data. * src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros. (AF_SCRIPT_FALLBACK): Renamed to ... (AF_STYLE_FALLBACK): ... this. * src/autofit/afglobal.c: Include `hbshim.c'. Update use of `SCRIPT' and `STYLE' macros. (af_face_globals_compute_style_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'. Update. * src/autofit/afmodule.h (AF_ModuleRec): s/fallback_script/fallback_style/. * src/autofit/afmodule.c (af_property_set): Adapt handling of `fallback-script' property to set a fallback style. (af_property_get, af_autofitter_init): Updated. * src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros. * src/autofit/afranges.h: Update use of `SCRIPT' macro. * src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include `hbshim.c'. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `hbshim.c'. (AUTOF_DRV_H): Add `afcover.h'. * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Use pkg-config for all libraries needed by FreeType.
